The State Department announcement followed a decision it took over the weekend to order the departure of all non-essential diplomats from Kyiv.

A small number of embassy staff from Kyiv will relocate to Lviv, where they will provide limited consular services to Americans and keep communications open with the Ukrainian government, the Department said.

It also repeated warnings to private American citizens in Ukraine to leave immediately.
